Add Image in Java PostScript

Introduction

In this tutorial, we will explore how to add images to a Java PostScript document using the Aspose.Page for Java library. Aspose.Page is a powerful library that provides various features for working with PostScript files, allowing developers to manipulate and enhance their documents seamlessly.

Prerequisites

Before we dive into the tutorial, make sure you have the following prerequisites:

• Java Development Kit (JDK) installed on your system.
• Aspose.Page for Java library. You can download it here.
• A basic understanding of Java programming.

Import Packages

To get started, import the necessary packages in your Java project. Use the following code snippet as a reference:

import java.awt.geom.AffineTransform;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.FileOutputStream;
import javax.imageio.ImageIO;
import com.aspose.eps.PsDocument;
import com.aspose.eps.device.PsSaveOptions;

Step 1: Write Graphics Save

The first step involves writing the graphics save to the document. This ensures that any transformations or modifications made afterward can be rolled back if needed.

// The path to the documents directory.
String dataDir = "Your Document Directory";
// Create output stream for PostScript document
FileOutputStream outPsStream = new FileOutputStream(dataDir + "AddImage_outPS.ps");
// Create save options with A4 size
PsSaveOptions options = new PsSaveOptions();
// Create new PS Document with the page opened
PsDocument document = new PsDocument(outPsStream, options, false);
document.writeGraphicsSave();

Step 2: Translate and Transform

Next, translate the document and create a BufferedImage object from the image file. Apply a series of transformations like scaling and rotation using AffineTransform.

document.translate(100, 100);
// Create a BufferedImage object from the image file
BufferedImage image = ImageIO.read(new File(dataDir + "TestImage Format24bppRgb.jpg"));
// Create image transform
AffineTransform transform = new AffineTransform();
transform.translate(35, 300);
transform.scale(3, 3);
transform.rotate(-45);

Step 3: Add Image to Document

Now, add the transformed image to the document.

document.drawImage(image, transform, null);

Step 4: Write Graphics Restore

After adding the image, write the graphics restore to finalize the changes made.

document.writeGraphicsRestore();

Step 5: Close Current Page and Save

Close the current page and save the document.

document.closePage();
document.save();

Repeat these steps for adding multiple images or customize the transformations based on your requirements.
